AI Technical Summary

Technical Problem

Current wireless local area network (WLAN) technologies, specifically in multi-link devices (MLDs) operating under IEEE 802.11be standards, lack comprehensive procedures for reconfiguring setup links and managing traffic identifiers (TIDs) to links mappings, leading to inefficiencies in link management and throughput optimization.

Method used

The implementation of methods and apparatuses that facilitate the reconfiguration of setup links between multi-link devices (MLDs) in a WLAN, including the generation and transmission of a reconfiguration multi-link element to manage affiliations and updates of affiliated APs, and the use of TID-to-Link Mapping (TTLM) procedures to disable links effectively.

Benefits of technology

This solution enables efficient reconfiguration of setup links, improves link management, and enhances throughput performance by allowing dynamic adjustments to link affiliations and traffic mappings, thereby addressing the limitations of existing technologies.

Abstract

Methods and apparatuses for reconfiguration of setup links between multi-link devices (MLDs). An access point (AP) MLD comprises APs and a processor. The APs each comprise a transceiver configured to transmit on a link setup with a corresponding STA of a non-AP MLD. The APs are affiliated with the AP MLD for ML operation on the setup links. The processor is configured to generate a reconfiguration ML element that indicates affiliated APs that are to be removed from affiliation with the AP MLD. The transceivers are configured to transmit the reconfiguration ML element to the corresponding STAs of the non-AP MLD. The processor is configured to determine whether any of the affiliated APs that are to be removed remain affiliated after transmitting the reconfiguration ML element, and to update the element to indicate the remaining affiliated APs that are to be removed. The transceivers of remaining affiliated APs are configured to transmit the updated reconfiguration ML element to the corresponding STAs of the non-AP MLD.
